[petsc-dev] Mat assembly on GPUs ...

Is there any plans/interest in assembling AIJ matrices on GPUs?

I have a somewhat strangely balanced FE operator and I have each thread
block create one element matrix, one thread per integration point with an
expensive computation at each integration point. Then I assemble the
matrices on the CPU.

I want to parallelize assembly on GPU machines, with coloring or DD I
assume. Does anyone else care about this?

Thanks,
Mark
